Question
D) +x E) -x 5) A resistor and an ideal inductor are connected in series to an ideal battery having a constant inal voltage Vo. At the moment contact is made with the battery the voltage across the resistor is B) Vole. D) zero. (b) the voltage across the inductor is A) Vo. B) Vole C) Vo/2. D) zero. 6) A beam of electrons is accelerated through a potential difference of 10 kV before entering a region having uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the direction in which the electron is moving. If the magnetic field in this region has a value of 0.010 T, what magnitude of the electric field is required if the particles are to be undeflected as they pass through the region?Explanation / Answer
5) no current will flow in inductor just after connecting.
(A) I = 0 hence VR = 0
Ans(D)
(B) VL = V0 - VR= V0
Ans(A)
6) m v^2 /2 = q deltaV
(9.109 x 10^-31 ) v^2 / 2 = (1.6 x 10^-19) (10 x 10^3)
v = 5.93 x 10^7 m/s
E = v B = 5.93 x 10^5 N/C
